You have to provide a model instance to update. Try something like:

class getCompanyDetails(APIView):
    def get(self, request):
        comp = company.objects.filter(active = True)
        serializer = restGetCompanySerializer(comp, many=True)
        return JsonResponse({"allCompanies":serializer.data})

    def patch(self, request):
        # fetching company with given company_id
        company = company.objects.get(pk=request.data['company_id'])
        # passing company as first argument. This will invoke 
        #  ModelSerializer's 'update' method instead of 'create' method.
        serializer = restAddCompanySerializer(company, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return JsonResponse(serializer.data)
        return JsonResponse(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
